Update: humans cut Libratus lead down to $10/hand after 3.5 days of play. They players made some adjustments and might be paying off. Won’t say what those adjustments were, though can see more varied game preflop on the Twitch stream.

In any case, this morning was their best session by far. Jason Les made a couple of great calls with medium-pair hands when Libratus tried to bluff him allin after missing big draws. Still early.
